Putting -lm Before User Objects/Libraries on Link Line Can Impact Performance

Recommended linking model: icc/icpc/ifort [user objs] [user libs] [sys libs] Using -lm (the GNU math library) prior to user-created objects or libraries causes the GNU libm to be used instead of the Intel math library, impacting performance.
